Imessage not working to some of my contacts

Hello Estelle van Eeden,

Thanks for using Apple Support Communities.

If I understand your post correctly, you're unable to send a message to a particular contact. To help resolve this issue please delete the existing conversation and then create a new message thread.

If messages won't send to a certain person or you need help with group messages

Sometimes your messages won't send to a particular contact, or you might have issues with group messages. For example, you might reply to a group conversation and receive your own message. Or you might get a new phone number and see your old one listed as a recipient in an existing group conversation.

Delete the conversation* that has the issue and start a new conversation:

1. Open Messages and look at your list of conversations.
2. Swipe from right to left on the conversation you want to delete. Then tap Delete.
3. Open Messages, tap , and enter the phone number or email address of your contact or contacts.
4. Write a new message and tap send.

*When you delete a conversation, you won’t be able to recover it. If you want to save parts of conversations or their attachments, you can take screenshots. You can also touch and hold an attachment or message bubble, then tap More > Save.

If you can‘t send or receive messages on your iPhone, iPad, or iPod touch

Take care.
